LIQUID-DRAWING APPARATUS.

Specification of Letters Patent.

Patented Feb. 17, 1914.

Application filed November 29, 1910. Serial No. 594,782.

To all whom it may concern:

Be it known that I, JOHN J. TOKHEIM, a

citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented a new and useful Liquid-Drawing Apparatus, of which the following is a specification. I This invention relates to apparatus for drawing liquids and is especially adapted to handle liquids, as for instance vinegar and other liquids usually drawn from a barrel as they are sold to a customer.

The apparatus is especially adapted to be used in stores for dispensing the liquid where the barrels or other reservoirs may be placed in the cellar and the drawing means may be arranged upon a floor above.

'With this object in view, the apparatus includes a panel adapted to be attached to a wall or other support and having a vessel supported in the vicinity of its upper end, the panel is prererably made from sheet metal and the upper ends of pipes are connected with the said vessel and extend behind the panel which is provided with upturned edges which space the intermediate portion of the panel from the support whereby room is provided for the said pipes. One of the pipes is adapted to be connected or projected into a barrel or other tank containing the liquid to be drawn and the other pipe is connected with a suction pump of peculiar construction which will be eX- plained hereinafter. I That end of the pipe which communicates with the barrel is provided at a point within the vessel with an adjustable tube and that end of the pipe which communicates with the ptunp is provided at a point within the vessel with a float valve.

In the accompanying drawings, Figure 1 is a perspective view of the apparatus. Fig. 2 is a back view of the panel and supported parts of the apparatus. Fig. 3 is a vertical sectional view of the panel and attached parts of the apparatus. Fig. 1 is a side elevation of the suction pump with parts in section. Fig. 5 is an enlarged detail sectional view of a portion of the upper part of the vessel of the apparatus. Fig. 6 is a top plan view of a part of the upper end of the cylinder forming a component part of the pump. Fig. 7 is a sectional view of the upper part of the pump cylinder.

The liquid drawing apparatus includes a panel 1 which is preferably formed from sheet metal having upturned edge portions 2 adapted to bear against a wall or other support, whereby the intermediate portion of the panel is spaced from the wall and sufficient room is afforded to house pipes hereinafter to be described. A vessel 3 is connected with the panel 1 in the vicinity of the upper end thereof and is provided at its lowest point with a valved outlet 4t. A pipe 5 extends up behind the intermediate portion of the panel 1. The upper end of the pipe enters the top of the vessel 3 and is provided with an adjustable tube 5 which is located in the vessel. The other end of the pipe 5 is adapted to be projected into a barrel or other vessel containing the liquid to be drawn. A pipe 7 also extends up behind the intermediate portion of the panel 1 and enters the upper end of the vessel 3 and is provided at a point within the vessel 3 with a float valve The pipe 7 at its lower end is connected with a pump which will now be described. The pump includes a stand 8 which consists of a base portion 9 and a vertically disposed yoke portion 10 mounted upon the base portion. The lower end of a cylinder 11 is mounted upon the upper intermediate portion of the base portion 10 of the stand and the upper end of the cylinder 11 is closed by a cap 12. A piston 13 is mounted for reciprocatory movement in the cylinder 11 and a piston rod 14: is connected at its upper end with the piston and projects down below the lower end of the cylinder 11 into the space between the opposite sides of the yoke 10 of the stand 8. A head 15 is attached to the lower end of the piston rod 1 1 and is located between the opposite sides of the yoke 10 of the stand 8. The upper intermediate portion of the yoke 10 of the stand 8 is provided at its opposite sides with vertically disposed guidev perforations 16. Rods 17 are snugly and slidably received in the perforations 16 and at their lower ends the rods 17 are connected with the opposite ends of the head 15 and the upper portions of the rods pass through similar guide perforations in the cap 12 and the extreme upper ends of the rods are connected together by a handle grip 18 which is located above the upper end of the cylinder 11. The pipe 7 communicates with the interior of the cylinder 11 through the cap 12 thereon and the cap at its inlet port is provided with a check valve 19 and at its outlet port with a check valve 20.

The upper intermediate portion of the yoke 10 of the stand 8 is provided with a cup or depression 21 which is surrounded by the cylinder. The cup or depression is adapted to contain a lubricating oil which will keep the piston 13 in proper condition to exhaust the air from the cylinder 11 when reciprocated.

From the above description it will be seen that when the pipe 5 is projected into a barrel or other reservoir containing liquid and the pump is operated to create suction through the pipe 7 a vacuum will be formed in the vessel 3 and the liquid will flow up through the pipe 5 into the vessel. l Vhen the liquid comes in contact with the float valve 6 the valve closes against the end of the pipe 7 and the flow of the liquid is auto matically stopped. The pipe 7 is provided with a valve 22 which is then turned so that air is admitted into the upper portion of the pipe 7 and the top of the vessel 3. The valve 4 may then be opened and the liquid deposited in the vessel 3 may be permitted to pass out through the outlet thereof into a jug or other vessel. By reason of the fact that the pipe 7 connects with the cylinder 11 at a point between the piston 13 and the handle grip 1S suction through the pipe is created upon the down stroke of piston and consequently an operator gains much leverage which renders the operation of creating the vacuum comparatively easy. The cylinder 11 is preferably provided at its lower end with a cup 21 in which oil may be placed to maintain the piston 13 in a proper state of lubrication to effectually operate as an air suction means.

Having described the invention what I claim as new and desire to secure by Let ters Patent is In a pump, a cylinder; a head for the cylinder having a lateral oiiset communicating with the interior of the cylinder, the offset having an opening in its top; a valve mov able in the opening and comprising a threaded stem located in the offset; a nut on the stem and adapted to engage the offset to limit the opening movement of the valve; a casing inserted into the bottom of the offset in alinement with the valve the casing being removable to permit an adjustment of the nut; a valve operating in the casing; and a piston operating in the cylinder.

In testimony that I claim the foregoing as my own, I have hereto aihxed my signature in the presence of two witnesses.
